�AURRAY - TOBIASON, INC. Planning • Civil Engineenng • Landscape Architecture FROM: DAZE: Re: rvIE1VYORANDUM John Vazdanega, P.B. March 21, 1996 exalaEs 9 / 30 / 9 Use oP Staples as an Alternate to Naiis in Shear Rated Construction. Many builders are choosing w use staples as an alternxte to nails for sheathing attachmen� in wood framed construction. This has raised issues regarding the use of staples as subs[itu[es fnr the specified nailing in shea:walls, floor, and roof diaphragms. Based on fas:enervalues li:ted in the Council of American Buil��ing Officials (CABO) Report Number NER-272, staples may be substituted for nails as follow:;: • For specified 8d common or galvanized box nails, use 16 GA x 7/16" crown x 1 3/4" leg staples at 2/3 of the specified nail spacing. (example: for 8d a[ 6" o.c. use staples at 4" o.c.). For specified lOd common or galv;u�ized box nails, use 16 GA x 7/16" crown x I 3/4" leg staples at 1/2 of the specified nail spacing. (example: for !Od at 6" o.c. use staples at 3" o.c.). No[es: Staples must have � 1" minimum peneva[ion in[o [he framing beneach. The 1 3/4" leg length noted is for shea:hing up to 3/4" in thickness. Both legs of the smple must be embedded in the framing for full load ratine. Staple crowns should be flush with the she:ithing surface for full load rating. Adjust equipment to avoid setdng staples deeply beloH� the shea[hing surface. Fastener spacing along intertnediate members sli�ll be the same as for nails. Other gauge staplzs may be used with adjustment to [he reyuired on center spacing based on rated load capac;ry. Thcse guidelines are based on use of a 16 gauge stanle since this is the nost widely used in the field. Other fzstener types and sizes muy be used but are subject to review on an �ndividual basis. 626 • 128ih Sireet Southwest, Suite 107 • Everett, Washington 982i14-6368 • Phone (206) 513•2500 • Faz (206) 742•28?2
